Enhancement of the Accuracy of the Astronomical Measurements Carried on the Wide-Field Astronomical Image Data

摘要

The properties of wide-field astronomical systems along with specific visual data in astronomical images contribute to complicated evaluation of acquired image data. The main goal of this paper is to present the advanced processing of the images obtained from wide-field astronomical systems and to introduce the way how to enhance the accuracy of astronomical measurements on these systems. The paper also deals with the modelling of the space variant high order optical aberrations which increase towards margins of the field of view and which distort the point spread function of optical system and negatively affect the image quality.
